This invention has for its obj ectto improve uponthe constructionjofleather slices giving' perinanency to the shapeY of the insolesofas toaord a bearing' surface for the foot shaped. on. the last tofit the footand 'retainingfsuch shape and Viit throughout the life of the shoe.

Another object of the invention incident tothe foregoing is theavoidance of what is' known as running over consisting yof a lateraldisplacement of the foot, causing' it to overhang the edge of the sole.f rIhis object is accomplished by the perinanency oflthe recess formingthe bearing for the ball yof the foot, serving' to confine the footinplace p against such displacement.` v

JAnothery object of the invention is tol avoid the development of raisedridges along` the seams incidentto the displacement by wear of the usualcomposition fillerv between'the inner and outer soles.

Another object of the inventionv is to prolong the life of the shoe andto give greater ease and comfort tothe wearer by flattening'.

the sole beneath the ball of the foot and so enlarging' the area of thebearing' surface.

lith the above and other objects 'in view the invention consists ofthe,l shoe as herein claimed and all equivalents. Q

Referring to th'e"'ac'coiiipanying drawings, in which likecharactersofrefei'ence indicate like parts in different views, v y

Fig'. l is a perspective view of 'a shoe constructed in accordance withthis invention, dissected on Vits last to show; the sections thereof; iy f 1 .Figz 2 is a transverse section showing the appearance of theshoebefore the outsole is applied, the dotted line showing the amount of theinsole buifed away to permit it to lit flatly against the outsole and toproduce vthe wedge-like taperingthickness of the insole around thelocation of the bearing'fo'r the ball of the foot; y

Fig. 3 is a transverse sectional 'view of the insole showing the extraheavy materialr usedV to permitof the heavy buffing operation and toafford the solid foundation for the molded seat forV the foot; Y

- Fig. 4 is a 'transverse sectional view of the completed shoe on itslast;

Fig. 5 is a longitudinal sectional view of a part of theshoe on itslast.

In these drawings, 10 indicates a last to which is fitted Yaninsole l1and the upper 12 in the usual manner, the insole', however, being-x ofmuch greater thickness-'than is usual either .l as 'a single piecev orof built-'up 'construction'. v lnpractice it is found desirable to.` useavery- I "heavyi-insoleof outsolek leather, known as about seven-ironthickness, in'oi'der that. it' f may be'buifedaw'ay to amaterial`deptliat the high spot of the lastvcorresponding. '.witl'iVA the greattoe Joint of the foot.. Thisbuffing Y operation is performed after the"insole has been stitched 'to the upper, as in Fig. 2, and v after atriangular` sole leathe'i1 welt 9 has beenv cemented in the channeledgroove, as shown in this figure. The'bufliing' operation is continued toremove the protruding portion of' Vthe insole that is causedbythe highspot of4 the pattern corresponding lwith the ball. of'v the foot anduntil the parts are brought` to a flat-condition across the entire widthof the shoe; This, of course','varies the thickness" ofthe insole sothatV it isquite thin-directly A beneath the ballof the foot andincreases in thickness in all ldirections fi'om 'thatpoin't so as toproduce in effect a solid wedge'dike Y support for the foot on eitherside of saidpoint,l as shown in Fig. 4f, and to the front and` y rearthereof, as shown in Figf. 5.

The use of an extraheavy insole inakes'it possible to buff away in thismanner to obtain the solid molded support for thefoot without damagingthe insole and itv alsov permits of a heavy shouldered channel l'towhich theupper l2 and welt l5V are attached. l y

The outsolelt is stitched tofthewelt 15 in the usual manner, but,because ofthe insole having` been buffed flush with theedges ofthe seam,the twov soles `it'flat together without 'any intermediatepackingwor-lilling of cork or similar. composition as usual and, when sofitted and stitched, the outsole is flat across thel ball of the foot asthe transverse'curvature of" the last is accommodated by the wedge-likemolded insole. rlhis gives the shoe a broad vflat bearing extendingacross the entire foot,

making it easier and'inore comfortable for the wearer and increasing thelife of the shoe by showingbetweenthe twosoles constitutes a` y sheet ofwaterproof tar paper i6, which in no Way affects the problem ofmaintaining thev shape of the shoe.

The triangular sole leather welt 9 cemented in the channel groove isinno sense regardedy as a sole iiller and the expression without the useof interinediateiillei is used with this 1 meaning.

Withbthe solid foundation formedv by ,the

shaped insole supported directly"` by the flat outsole, there is nopossibilityof the insole sagging into arecess Vbeneathit, asisicorn#Inonly done whenthe weight of the wearer; J conipactsand displac-esforwardly'andV rear- 15 wardly the cork or other conipositionillerbetween the insole andthe outsole of shoes asordinarlly constructed.vfinch sagging oftheulnsole increases the sectional area of the shoeasa'container so that it no longerrestig'ains the foot against lateraldisplacement and leaves the arch' of the foot unsupported, creating a yy.tendencyto ybroken arches, while the niore rigid seams stand vasraised ridges to wear callouses at the edges of the foot.

All of this 1s overcome in the shoe ofthis invention bythe rigid ornon-colnpressible and non-displaceable solid wall-of varying thickv'ness formed by the two soles fitting together in face tofface Contact,for the shape produced by the molding of the insole to the last isperinanently retained by the reinforcement backing afforded by theoutsole-bearing directly thereagainst acrossthe entire width of the encyfor the foot to stretch the upper and,

therefore without causing overrunning of the upper. The shoe retains itsshape as well asrits fit l while the walking surface remains level v'andWear is retarded by being ,distributed over a greater surface.y f. f v vl What I clannas new and desire to secure by Letters Patent is: Y 'f l.YIn a shoe,van insole shaped to dallast toA have its upper surfacecorrespond with the curvatures of the bottoin of the last, an upper' anda welt stitched thereto, said insole being A .fa 50 Y reduced andflattenedat itsv lower surface be" neath the high spot'of the lastcorresponding withth-e ball of the foot, and asole ineniber fittedthereto and stitchedito the weltwith the flat surface ofthe insoledirectlyv bearing thereon. v 2. In a shoe, an insole increasing 1nthicke ness forwardly and rearwardly vand toward either side from apoint corresponding with the ball of the foot and provided with a shoulidered channel, an upper'and welt stitched to the shouldered channel ofthe insole,y a triangular sole-leather welt secured within the`r`channel Oroove, and another solevsecured in 'face to face Contact withthe insolei f In testimony whereof, I affix iny signature. -j
